There seems to be a bit of controversy surrounding cylinder sleeves and BMW engines. Oil consumption, excessive noise, sleeves dropping, Alusil blocks not liking sleeves – you name it. I took some time to talk to our machine shop foreman, (the man with 50 years experience) Tony (VAC owner) and our manufacturing partners (Darton and LA Sleeve) about the drawbacks of using sleeves in the S54, S62 and S65 engines.
Short answer: There are no drawbacks.
